SPECIFICATION forming part of Letters Patent No. 399,216, dated March 5, 1889.

Application filed June 27, 1888. Serial No. 278,377! (No model.)

1'0 a/ZZ whom it may concern:

Be it known that I, JosnPH Seances, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,

have invented certain new and useful Improvel ments in Sash-Balances, of which the following is a specification, to wit:

My invention relates to certain improvements in sash-balances; and it consists in certain peculiarities of the construction and arrangement of the same, as will be more fully set forth and claimed.

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in which- Figure l is a plan view with my device in place ready for. operation. Fig. 2 a detail view of the cord-holding sleeve and catch, showing the curved shank. Fig. 3 is a sectional side view showing the eye-plate in position on the sash and the recess or depression for the reception of the hook or catch and cord-sleeve. Fig. l is a side view showing the device in position to be detached.

(i represents the side bar of the sash, having the usual groove, '12, for the reception of the cord. At a suitable distance from the top of the sash this groove terminates in a recess, r, cut or niortised in the side of the sash adjacent to the sash-frame, for the reccpiion and retention of the cord-sleeve, catch,

and eye-plate, as will be presently explained. i This recess is formed with a depression sutlicient to allow the eye-plate and cord-sleeve and catch to tit snugly and to be flush with the outer surface of the sash when the device is locked. The upper portion of the recess is formed tapering, with the smaller portion toward the top of the sash and the lower portion square, or nearly so, as seen in. Fig. 1 of the drawings. At the lower portion of the recess I provide a deeper depression with an incline, (I, as seen in Fig. 3. The objectof this incline is to force the tongue of the catch up against the inwardly-projecting portions 7 of the eye-plate, when the catch is inserted in the T-shaped eye.

e is a bed-plate, having shoulder f and T- shaped eye 9, and is firmly attached to the frame of the sash by means of screws.

71 is a cord-holding sleeve, inade, preferably, of a tapering form, with a funnel-shaped hole for the easy passage of the cord through the same, and for holding the core securely I when a knot is tied in the lower end. At the lower end of the cord-sleeve, and flush with the top, I provide projections 1', which rest on the shoulder f of the eyepla-tc.

It is a curved shank connecting the projections of the cord-sleeve with the tongue I. This shank is curved, as shown, for the piirpose of giving a firmer pressure to the tongue against the under side of the eyeplate, acting as a lever on the shoulder f of the eyeplate.

and affords an easy method of removing the sashes when it is desired to glaze or cleanse the glass.

To remove the sash it is neijeessary to detach the beading froin the sash-frame and i draw the sash inward, or toward the operator. I Then by slacking the cord and drawing the cord-sleeve down to a right angle with the frame the catch is readily removed. To fasten or lock the device, the cord-sleeve is held at a right angle with the sash and the tongue is "inserted in the eye till it reaches the bottom of the cavity, when the cowl-sleeve is pressed upward into the socket tor its reception, the i cord tightened, and the sash replaced.

I Having thus fully described my invention, f what I claim as new, and desire to secure by 3 Letters Patent, is

1. In a sash-balance, the combination of the bed-plate c with the sash a, and cord-holding l sleeve h, having a curved shank, Ir, and tongue Z, engaging with the bed-plate a, substantially as shown and described, and for the purpose set forth.

2. In a saslrbalance, the combination of the bed-plate 6, formed with a depressed flange or shoulder, f, and having a T-forined eye, 9, a cord-holding sleeve, 71, having acurved shank, Zr, and tongue 1, adapted to engage said eye g, and the sash a, formed with a depression, 0, for the reception of the plate and cordsleeve and tongue, substantially as shown and described, and for the purpose set forth.
